| |
| ## Before you begin |
| |
| Read the general instructions in the [root README.md file](/README.md) for setting up your environment and the Kubernetes cluster before looking at this example. |
| |
| Make sure you've read the [installation instructions](https://camel.apache.org/camel-k/latest/installation/installation.html) for your specific |
| cluster before starting the example. |
| |
| ## Understanding the Example |
| |
| - [`Env.java`](./Env.java) defines a route that logs the value of an env variable every second |
| |
| ## Running the Example |
| |
| To both set the `MY_ENV_VAR` env variable to `hello world` and run the integration, execute the following: |
| ``` |
| kamel run --dev --env MY_ENV_VAR="hello world" Env.java |
| ``` |
| You should see `hello world` logged to the terminal every second |
